Following the procedure as describe in Example 8, making variations as required to replace benzylamine with ethylamine to react with 4-methyl-2-(2-oxo-3-(4-(trifluoromethoxy)benzyl)imidazolidin-1-yl)thiazole-5-carboxylic acid, the title compound was obtained as a white powder in 25% yield: mp 218-219° C. (ethyl acetate/hexanes); 1H NMR (300 MHz, CDCl3) δ 7.32 (d, J=8.4 Hz, 2H), 7.18 (d, J=8.4 Hz, 2H), 5.60 (s, 1H), 4.47 (s, 2H), 4.10-4.04 (m, 2H), 3.51-3.35 (m, 4H), 2.57 (s, 3H), 1.18 (t, J=7.5 Hz, 3H); 13C NMR (75 MHz, CDCl3) δ 162.3, 157.0, 155.4, 152.3, 148.9, 134.4, 129.7, 121.4, 120.4, 117.8, 47.3, 42.0, 41.8, 35.1, 34.8, 17.0, 14.8: MS (ES+) m/z 429.2 (M+1).
